Definitions
- the present invention relates to a laxative containing composite magnesium oxide particles as an active ingredient. More specifically, the present invention relates to a laxative comprising as an active ingredient composite magnesium oxide particles obtained by adding a small amount of zinc (Zn) to magnesium oxide particles.
- a laxative comprising as an active ingredient composite magnesium oxide particles obtained by adding a small amount of zinc (Zn) to magnesium oxide particles.
- Laxatives containing magnesium oxide particles as active ingredients are manufactured and sold as tablets, granules or capsules. In order to obtain a sufficient laxative effect, this laxative had the problem that it was necessary to take a large amount of magnesium oxide particles and it was difficult to take. In addition, conventional laxatives stimulated the intestines and caused peristalsis to promote laxative action, so they were accompanied by abdominal pain and side effects such as damaging the intestinal wall when taken for a long time.
- Patent Document 1 a laxative agent composed of magnesium oxide particles, a binder capable of exhibiting a laxative action and a disintegrant capable of exhibiting a laxative action has been proposed.
- Patent Document 2 a laxative tablet that has excellent acid reactivity and does not directly irritate the intestine by making the specific surface area of the magnesium oxide particles within a specific range.
- Patent Document 2 a laxative tablet that has excellent acid reactivity and does not directly irritate the intestine by making the specific surface area of the magnesium oxide particles within a specific range.
